MACHINE FOR MOVING IRON AT THE ROLLS.

Specification of Letters Patent No. 24,304, dated J une 7, 18,59.

To all whom it may concern.:

Be it known that I, CHARLES IjIEWrrT, of the city of Trenton, in thecounty of Mercer and State of New Jersey, have invented a new andImproved Mode of Moving Iron or other Metal Vhile the Same is in Processof Manufacture at the Rolls; and I do hereby declare that the followingis a full, clear,

and exact description thereof, reference being had to the annexeddrawings, making a part of this specification, and which represent twomodes of applying my invention, one of which is shown Figs. l and 2,which are respectively an end and side elevation. The other is shownFigs. 3, 4L, and 5, Fig. 3 being a side elevation, Fig. I an end view,and Fig. 5 a plan.

Similar letters of reference indicate corresponding parts in the severalfigures.

I will now proceed to explain the iirst and most simple application ofmy invention which is shown Figs. 1 and 2. The iiows A and B of Figs. 1and 2 are represented at a level midway between their highest and lowestpositions, and resting on rollers.

The floor A Figs. l and 2 rests on the rollers a aA a a a a and thefloor B Fig. 2 on rollers Z) b b Z) b o (see Fig. l). These rollers areattached to the levers 0 o c &c. and the levers c o o &c. These levershave for their fulcrums the shafts d Z CZ d and from them are suspendedthe weights w w w &c. Before explaining the operation of these parts itis necessary to state that in practice it is found best to have thelower surface of the pile or piece to be rolled, while on the enteringside, below a plane that is tangent to the roll, on which the iron orother metal is to be entered, or in other words the center of the pileshould be lower than the center of the groove, so that in entering, theend of the pile will first strike the lower roll of the two betweenwhich it is to be passed and be carried upward by it into the groove.lThe opposite side however or, that upon which the metal is to bedelivered, should be tangent or nearly so to the lower of the two rollso. Therefore the floor from which the metal'is to be entered must alwaysbe lower than that upon which it is to be delivered. As A is theentering side when the floors are in their lowest position, it must thenbe lower than B, but as it is the receiving side when thefloors arehighest, it

must then be higher than B. Hence B never ascending as high nordescending as low as A has less motion than the latter. On thisdifference of motion depends one important feature of myinvention-namely, the raising as well as the lowering of the metalwithout the use of other power than gravity. If the rolls are thirtyinches in diameter A may be made to have a motion of thirty four inchesand B of twenty six inches. The mode of accomplishing this difference inthe movement of the. two floors may be seen by referring to the rollersa a a &c., b Z) Z9 &c., the distance of the fulcrum d from the latterbeing so much less than from the former, as to produce the desiredeffect, the weights, levers and fulcrums being all so connected as toaffect each floor at the same time, but not to the same degree. As theiron or metal to be rolled alwaysl descends on floor A which has thergreater motion and rises on floor B which has the less, it is easy tosee that the floors, men, and the metal to be rolled may lift thecounterbalances in the one case, and be lifted by them in the other.

To operate this form of my invention the metal to be rolled is broughtto A Figs. 1 and 2 while the lioors are in their lowest position, and isentered bythe workmen into the rolls, and discharged by them upon B Fig.2. The weights w, w w &c. in the manner already explained now lift thefloors, men and metal to the requisite height for making the second passby which the metal ing their self-act-ingcharacter seriously, and

possibly even the backward and forward movements similar to what ishereafter described and shown Figs. 3, I and 5, which represent thesecond and more complete form of my inventiona form which renders itunnecessary to have men on the floors to enter or move the metal afterit has been brought to, and passed Vthrough thefirst groove of therolls. One man only 1s required to operate the floors. I-Ie need nothowever stand upon them, but may beat any convenient distance where hemay see but not be affected by the heat of the bars in process ofmanufacture.

I will proceed to describe the construction and operation of thisapplication of my invention. The met-al is rst brought to floor A Fig. 3and entered in the first groove. Passing through this it is dischargedon floor B of Fig. 3. Then the workman in charge throws the clutch e,which works on a feather in the shaft, into gear with the wheel f whichis loose on its shaft. This wheel thus receives motion which itcommunicates to the wheel g, to its shaft, and through the latter to thedisks ZL 7L. These disks impart motion to the connecting rods z' i i z'and they by their connection with the arms y y y y to the shafts 7c 7c7c &c., all of these shafts being connected by the rods Z Z Z &c. andarms m, m, 'm &c. When the movement begins the shafts v 7c 7c &c. allturn on their axes, the arms n, n, n Sac. rotating upward and liftingthe framework 0 0 &c. and the ioors, at the same time carrying thembackward and from the rolls, so far that the end of the bar being rolledmay not strike the restip. Then the shafts ,7c 7c &c.are preventedV fromrotating further by the guiding pins in the arms g g g &c., theseguiding pins .working in the slots i shown in the drawings. These slotsare so shaped that the action of the guiding pins in them preventsfurther rotation of the shafts than I have described, but enables themall to receive a forward motion toward the rolls upon the wheels r '1 r&c., the floor above and the iron on it receiving a similar movement. Inthe meantime the irregularly-shaped stationary pieces s s s s by theirraction on the movable parts t t cause the upper part ofthe floor orfioor proper to roll on the wheels m' &c. far enough sidewise to carrythe metal opposite the second groove of the rolls. The floors will atthis time be in the position shown by the drawings.`

The forward movement above described is greater in distance than thebackward movement of the same Hoor while rising, and thereby theentering of the metal in the sec ond groove is secured, through which itpasses and is discharged upon the floor A Fig.V 3. Then the operatorthrows the clutch' u, which works on a feather into gear with thelowerwheel 0, which like the wheel f also communicates motion to thewheel g,

but in the opposite direction, thus reversing `the motion on all theparts of the oors and connections.

It is to be noticed that the backward motion of floor A Fig. 3 is lessthan the for- `ward motion it receives inits descent, thereby securingthe entering of the metal in the third groove. The subsequent part ofthe operation is a'mere repetition of the movements already described.``With this mode of applying my invention, the use of power in additionto gravity is necessary, but in order that the full benefit of thelatter may be had, the weights, W W are provided and are so graduated asto make it unnecessary to expend more power in lifting than in loweringthe oors.

The mode of originating the floor movements through the agency of theclutches e and fmand the wheels f, fu, and g, has been set forth andshown in the specification and drawings more for the purpose of havingthem agree with the model which it was con venient thus to make, than asthe best mode of construction. I believe it would be preferable to havethe machinery for moving the floors entirely disconnected from, and independent of, that which drives the rolls.

Among the advantages resulting from my invention are 1, a saving oflabor and power; 2, the removal of all limitations upon the size andstrength ofjrolls to be used; 3, `the provision of means for making barsor plates of any size that may be required, as the success of theoperation does not depend upon the ability of men to handle the weightof, or endure the heat radiated from large masses of metal, butonly uponthe size, strength and power of the machinery employed'; t, aproductbetter and more uniform in quality, as the rolling will be morequickly done, and while the metal is at a heat favorable for good andreliable work.

What- I claim as my invention and desire to secure by Letters Patent isl The movable floors, platforms, orY supports A B for moving iron orother metal at the rolls, while in process 'of manufacture, constructedand operated as herein described, or otherwise substantially the same.
